IPC: F16H3/72
Filed: 1981-05-23
Abstract: PURPOSE:To enable stepless change of speed by providing a ring gear of a planetary-gear system with a worm gear meshed with a work drivable by a motor. CONSTITUTION:When a planetary carrier 5 mounted on an input shaft 9 is turning at a low speed by the power from an engine, a ring gear 3 also turns in the same direction as the planetary carrier 5 via a worm gear 7 and a worm 1 by a motor and therefore the rotation of the planetary carrier 5 is not transmitted to a sun gear, thus temporarily interrupting the transmission of the power. If the engine speed is increased or the speed of a motor 2 is reduced, the rotating speed of the sun gear gradually increases to change the speed.

Filed: 1989-03-29
Abstract: PURPOSE:To realize high resolution at a low cost and to make the focus correction of a zoom lens and the like excellent by providing two resistors, moving bodies which are moved in parallel, and sliders which are attached to the moving body. CONSTITUTION:At first, in a range from (a) to (b), the output voltage from a slider 7 that is slidden on a resistor 3 to which a power source 11 is connected is taken out of an output terminal 9. Thus, the position information is detected. In a range from 0 to (a), high resolution is required. Therefore, a resistor 4 to which the power source 11 is connected is used, and the high resolution is realized. The position resolution which is obtained through a position detector using one resistor is limited by the error in resistance value of the resistor, the revolution of an A/D converter which detects the output voltage and the like. On the contrary, when at least two resistors are used, the higher resolution can be realized.
